IMPROVEMEET IN ATTAGHING BOLSTERS TO KNIVES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY BARBER, of Greeneld, Franklin county, Commonwealth oi Massachusetts, have invented certain new and useful Improvements in Fasteningon Knife-Bolsters; and I do hereby declare that the following is a. full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. In thedra-wings- Figure 1 is a. sectional,

Figure 2 a plan, and

.Figure 3 a detail view of my improvements.

This invention consists in a new and improved method of fastening the holsters of knives upon the tang, whereby they are more durably and neatly attached.

In construction, I form the holsters A (which are pieces placed on each side of the tang'B at its junction with the blade) each with projections a a and b b', the ones a and a heing on one bolster, while the projections bb are on the other. The holsters which are used as shoulders for the ends of the scales to come against, are hollowed out on their inside surfaces, and have the projections formed one on each side of this hollow.v The tang B has notches c ccut in its sides, so that the edges of the holsters may come together at each side, and alsothat the projections a a and b b may he clinched on each side of the tang, in the manner shown in fig. 1.

These projections are not placed opposite to each other exactly on the sides of the holsters, hut one of them is brought a little further forward on each bolster. This is to allow the four projections to be clinched neatly and compactly together, which lis necessary in order to get them enclosed in the hollows in the insides of the holsters.

The manner of operating these pieces having the projections is as follows: They are placed in the proper positions on each side of the tang, and then are pressed together hy suitable machinery, which curls the' projections around on each side of` the tang, the hollows in the holsters allowing them room, so that the edges of the holsters may come neatly and compactly together.

By this means I robtain a simple and eiective method of fastening on the holsters firmly and' compactly, I

being also a much more economical manner than the usual one of riveting, dove-tailing, &c.

And now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is- Attaching the holsters upon the tang by means of projections a a and b b upon each side of. the holsters, the projections being clinched on the top and bottom sides of the tang, substantially as and for the purpose shown.

i HENRY BARBER.
